The absolute valuesof both + and - voltages are input, and a force limit value corresponding to that absolute value is applied in theforward and reverse direction./P-CLOFF ON/N-CLOFFONPn483Pn4840ForceSpeedPn4840Pn404Pn483ForceSpeed0Pn484Pn405Pn483ForceSpeed0Pn484Pn405Pn404Pn483ForceSpeedParameter Meaning When Enabled ClassificationPn002 n.1 Uses the T-REF terminal as an external force limitinput.
